I would try using a more complete nutrient to cover all your bases incase it's not a pottasium def, and another problem.

Try FloraNova from General Hydroponics. It has so many different macro and micro nutrients in it, it will more than likely help clear up any deficiencies you have.

First though, you might want to flush the plant with plain water for a couple days to prepare the plant for the new nutrients.

May I refer you to this:

After you see what the correct ratios are you'll quickly notice why your plant is burned from too much p.

looks like ne deff on the plant but the leves that you have over the white paper look like something else.........
